Success control
The success control is a central component of quality assurance in the realization and operation of low-noise semi-dense asphalts (SDA).
It ensures that the technical, functional, and acoustic properties of the pavement meet the requirements after production, during installation, and in operation, and are maintained throughout the entire service life.
An effective control system begins with the testing of materials, continues through the monitoring of the mix and installation, and extends to the assessment of acoustic performance in operation. The following sections provide a practical overview of the relevant testing contents and their significance.
For practice, this means:
- Early material testing to ensure quality
- Continuous production and installation controls
- Systematic surface and acoustic measurements in operation
This ensures that the investment in low-noise pavements fulfills its purpose in the long term, lessons are learned from mistakes, and technologies and practices can continuously evolve.
